html5 - javascript chart library that supports the "follows" on line charts with mobile -

i looking html5/css/javascript chart library supports "follows" on line charts mobile. precise on refering "follows" on line charts, here examples:

• http://code.shutterstock.com/rickshaw/examples/extensions.html
• https://google-developers.appspot.com/chart/interactive/docs/gallery/trendlines

even different, 1 nice also

• http://www.flotcharts.org/flot/examples/tracking/index.html

i have made tests using extensive comparison provided here. unfortunately, not able find line chart demo "follows" worked "out-of-the-box" both chrome , chrome android. chrome targeted browser now, writing non commercial app fun.

it seems of these implementations based on :hover css selector not available mobile. tried bind :hover logic "touchmove" not straightforward (with rickshaw @ least).

my question is: missing library or option in existing libraries or should keep on trying implement custom logic ?

you missed amcharts in list, support "follows", example: http://www.amcharts.com/javascript-charts/line-with-duration-on-value-axis/

note, should set chart.paneventsenabled = true in order touch events work on mobile.
